This invention relates to tools and more i f particularly to a laying-out tool 01' gauge for rolled metal H beams and the like, and has for its object the provision of a gauge that 5 may be used to layout points on beam webs at the same distance from the outside faceof the beam flanges without figuringthe flange thickness, regardless of the thickness of the beam flanges.

mension-s are the same for various weights and the varying weights are produced by varying the thickness of the flanges and webs. In fabricating beams of this class itis generally the practice to lay out thewebs for punching and other work by indicating this distance of the layout'points from the outside face of the flanges, since the outside or overall dimensions of the beams are constant for various sizes of beams. Heretofore, when using standard tools or scales it has been necessary for the workman to figure the thickness of the flange and then mentally calculate the layout points on the standard scale. The present invention eliminates the necessity for this mental calculation With. its chances of error and insures accuracy While at the same time speeding upthe' work materially.
